therefor) at the rate of six and one-half per cent (6.50%) per annum, from
February 8, 1999, payable quarterly in arrears on the first day of February,

have become due.  Interest shall be computed on the basis of a 360-day year of
twelve 30-day months.

Payment Date occurs, and, in the case of interest payable at the Stated

bond (or one or more predecessor bonds) of record at the close of business on a
special record date (the "Special Record Date") fixed by the Trustee for the
payment of such defaulted interest, notice whereof shall be given to Holders not
less than 10 days prior to such Special Record Date, all as more fully provided

of Section 7.04 of the Twentieth Supplemental Indenture hereinafter described,
be payable at the office of State Street Bank and Trust Company, in Boston,

Twentieth Supplemental Indenture) with respect to the bonds shall occur and be
continuing, the principal plus any accrued interest may be declared due and

principal of all the bonds of each and every series issued and outstanding
thereunder may be declared or may become due and payable in the manner and with
the effect provided in the Indenture.

     No recourse shall be had for the payment of any part of either the
principal of or interest on this bond, or for any claim based hereon, or
otherwise in any manner in respect hereof or in respect of the Indenture, to or
against any stockholder, officer or director, past, present or future, of the
Company, by virtue of any statute or provision or rule of law, or by the
enforcement of any assessment or penalty, all such liability being expressly
waived and released by the acceptance of this bond.

     This bond shall not become obligatory for any purpose until authenticated
by the execution by the Trustee of the certificate endorsed hereon.

                            STATEMENT OF INSURANCE

     The MBIA Insurance Corporation (the "Insurer") has issued a financial
guaranty insurance policy (the "Policy") containing the following provisions,
such Policy being on file at State Street Bank and Trust Company.

     The Insurer, in consideration of the payment of the premium and subject to
the terms of the Policy, hereby unconditionally and irrevocably guarantees to
any owner, as hereinafter defined, of the following described obligations, the
full and complete payment required to be made by or on behalf of the Company to
State Street Bank and Trust Company or its successor (the "Paying Agent") of an
amount equal to (i) the principal of (at the stated maturity) and

                                       5


interest on, the Obligations (as that term is defined below) as such payments
shall become due but shall not be so paid (except that in the event of any
acceleration of the due date of such principal by reason of mandatory or
optional redemption or acceleration resulting from default or otherwise, the
payments guaranteed hereby shall be made in such amounts and at such times as
such payments of principal would have been due had there not been any such
acceleration); and (ii) the reimbursement of any such payment which is
subsequently recovered from any owner pursuant to a final judgment by a court of
competent jurisdiction that such payment constitutes an avoidable preference to
such owner within the meaning of any applicable bankruptcy law. The amounts
referred to in clauses (i) and (ii) of the preceding sentence shall be referred
to herein collectively as the "Insured Amounts." "Obligations" shall mean:

                                  $15,000,000
                          The Providence Gas Company
                    Senior Secured Insured Quarterly Notes
                      Due February 1, 2029 (IQ Notes/SM/)

     Upon receipt of telephonic or telegraphic notice, such notice subsequently
confirmed in writing by registered or certified mail, or upon receipt of written
notice by registered or certified mail, by the Insurer from the Paying Agent or
any owner of an Obligation the payment of an Insured Amount for which is then
due, that such required payment has not been made, the Insurer on the due date
of such payment or within one Business Day after receipt of notice of such
nonpayment, whichever is later, will make a deposit of funds, in an account with
State Street Bank and Trust Company, N.A., in New York, New York, or its
successor, sufficient for the payment of any such Insured Amounts which are then
due.  Upon presentment and surrender of such Obligations or presentment of such
other proof of ownership of the Obligations, together with any appropriate
instruments of assignment to evidence the assignment of the Insured Amounts due
on the Obligations as are paid by the Insurer, and appropriate instruments to
effect the appointment of the Insurer as agent for such owners of the
Obligations in any legal proceeding related to payment of Insured Amounts on the
Obligations, such instrument being in a form satisfactory to State Street Bank
and Trust Company, N.A., State Street Bank and Trust Company, N.A. shall
disburse to such owners or the Paying Agent payment of the Insured Amounts due
on such Obligations, less any amount held by the Paying Agent for the payment of
such Insured Amounts and legally available therefor.  The Policy does not insure
against loss of any prepayment premium which may at any time be payable with
respect to any Obligation.

     As used herein, the term "owner" shall mean the registered owner of any
Obligation as indicated in the books maintained by the Paying Agent, the
Company, or any designee of the Company for such purpose.  The term owner shall
not include the Company or any party whose agreement with the Company
constitutes the underlying security for the Obligations.

                                       6


     Any service of process on the Insurer may be made to the Insurer at its
offices located at 113 King Street, Armonk, New York 10504 and such service of
process shall be valid and binding.

     The Policy is non-cancelable for any reason. The premium on the Policy is
not refundable for any reason including the payment prior to maturity of the
Obligations.

     The insurance provided by the Policy is not covered by the
Property/Casualty Insurance Security Fund specified in Article 76 of the New
York Insurance Law.

     Any provision of the Indenture may not be amended in any manner which
materially adversely affects the rights of the Insurer hereunder without the
prior written consent of the Insurer, which may not be unreasonably withheld,
conditioned or delayed.

     IN WITNESS WHEREOF, THE PROVIDENCE GAS COMPANY has caused its corporate
seal to be hereto affixed and this bond to be signed by its President or Vice
President and its Treasurer or Assistant Treasurer, the 8th day of February,

     principal amount of the Global Note in exchange for such Global Note. The
     Trustee shall not be charged with knowledge or notice of the ineligibility
     of a Depository unless a Responsible Officer of the Trustee shall have

     bonds in definitive registered form in any authorized denominations and in
     aggregate principal amount equal to the principal amount of the Global
     Notes in exchange for such Global Notes.

          (iii) In any exchange provided for in either of the preceding two
     paragraphs, the Company will execute and the Trustee will authenticate and
     deliver individual Notes in definitive registered form in authorized
     denominations. Upon the exchange of a Global Note for individual Notes,
     such Global Note shall be canceled by the Trustee. Notes issued in exchange
     for a Global Note pursuant to this Section shall be registered in such
     names and in such authorized denominations as the Depository for such
     Global Note, pursuant to instructions from its direct or indirect
     Participants or otherwise, shall instruct the Trustee. The Trustee shall
     deliver such Notes to the Depository for delivery to the Persons in whose
     names such Notes are so registered, or if the Depository shall refuse or be
     unable to deliver such Notes, the Trustee shall deliver such Notes to the
     Persons in whose names such Notes are registered, unless otherwise agreed
     upon between the Trustee and the Company, in which event the Company shall
     cause the Notes to be delivered to the Persons in whose names such Notes
     are registered.

     (d)  None of the Company, the Trustee, any authenticating agent or any
Paying Agent shall have any responsibility or liability for any aspect of the
records relating to, or payments made on account of, beneficial ownership
interests of a Global Note or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

then upon surrender to the Trustee of such Global Note, the Company shall
execute, and the Trustee shall authenticate, deliver and register, a Global Note
in an authorized denomination in aggregate principal amount equal to, and having
the same terms, Original Issue Date and series as, the unpaid portion of such
Global Note.

accrued interest) the Series T bonds shall cease to bear interest.  If any
Series T bond called for redemption shall not be paid upon surrender thereof for
redemption, the principal shall, until paid, bear interest from the Redemption
Date at 6.50%. Subject to the foregoing and applicable law (including without
limitation, United States federal securities laws), the Company or its
affiliates may, at any time and from time to time, purchase outstanding Series T
bonds by tender, in the open market or by private agreement.

     Section 4.03.  Redemption Procedures.  Except as herein otherwise set
forth, the provisions of Article Fourth of the Original Indenture, with respect
to the procedures for call and redemption, prior to maturity, of Series A and
Series B bonds, shall apply to the call and redemption, prior to maturity, of
all bonds of Series T so to be called and redeemed pursuant to Section 4.02.
All Series T bonds redeemed pursuant to the provisions hereof shall be canceled
by the Trustee and shall be delivered to or upon the order of the Company, and
shall not be reissued.

     Whenever any Series T bonds are to be redeemed pursuant to Section 4.02,
the Trustee shall allocate to each Registered Owner a proportion of the Series T
bonds to be redeemed, equal, as nearly as practicable, to the proportion that
the principal amount of the Series T bonds then outstanding hereunder,
registered in the name of such Registered Owner, bears to the principal amount
of all Series T bonds then outstanding under the Indenture.

     Redemption notices for Series T bonds shall be given to each Registered
Owner by registered mail and not by publication.  The redemption notice given to
each Registered Owner shall comply with the provisions of Article Fourth of the
Original Indenture and shall also specify (i) the principal amount of such
Registered Owner's Series T

                                       18


bonds to be redeemed, and (ii) the accrued interest payable in connection with
such redemption.

     Section 4.04.  Redemption at the Holder's Option. For purposes of this
Section 4.04 a "Beneficial Owner" means the person who has the right to sell,
transfer or otherwise dispose of an interest in Series T bonds and the right to
receive the proceeds therefrom, as well as the interest and principal payable to
the Holder thereof. In general, a determination of beneficial ownership in the
Series T bonds will be determined by the Company, in its sole discretion, which
determinations shall be final and binding on all parties.

     Unless the Series T bonds have been declared due and payable prior to their
maturity by reason of an Event of Default, the personal representative or other
Person authorized to represent the estate of the deceased Beneficial Owner or
from a surviving joint tenant(s) or tenant(s) by the entirety (each, a
"Representative") of a deceased Beneficial Owner has the right to request
redemption prior to February 1, 2029 of all or part of such interest, expressed
in integral multiples of $1,000 principal amount, in the Series T bonds, and the
Company will redeem the same subject to the limitations that the Company will
not be obligated to redeem, during the period from the Original Issue Date
through and including February 1, 2000 (the "Initial Period"), and during any
twelve-month period which ends on and includes each February 1 thereafter (each
such twelve-month period being hereinafter referred to as a "Subsequent
Period"), (i) on behalf of a deceased Beneficial Owner any interest in the
Series T bonds which exceeds an aggregate principal amount of $25,000 or (ii)
interests in the Series T bonds in an aggregate principal amount exceeding
$375,000.  A request for redemption in the form attached as Schedule III hereto
may be initiated by the Representative of a deceased Beneficial Owner at any
time and in any principal amount in integral multiples of $1,000.
Representatives of deceased Beneficial Owners must make arrangements with the
Participant through whom such interest is owned in order that timely
presentation of redemption requests can be made by the Participant to the
Trustee.  If the Company, although not obligated to do so, chooses to redeem
interests of any deceased Beneficial Owner in the Series T bonds in the Initial
Period or any Subsequent Period in excess of the $25,000 limitation, such
redemption, to the extent that it exceeds the $25,000 limitation for any
deceased Beneficial Owner, shall not be included in the computation of the
$375,000 limitation for such Initial Period or such Subsequent Period, as the
case may be, or for any succeeding Subsequent Period.  Any Series T bonds (or
portion thereof) tendered pursuant to a redemption request may be withdrawn by a
written request by the Representative received by the Trustee at least ten (10)
days prior to its repayment.

     Subject to the $25,000 and $375,000 limitations, the Company will, after
the death of any Beneficial Owner, redeem the interest of such Beneficial Owner
in the Series T bonds on the next Interest Payment Date following receipt by the
Trustee of a redemption request

                                       19


received at least twenty (20) days in advance of the next Interest Payment Date.
The Trustee will notify the Company promptly after receipt of any redemption
request and the Company will provide all funds necessary for such redemption
prior to the date of redemption to the Paying Agent. If redemption requests
exceed the aggregate principal amount of interests in Series T bonds required to
be redeemed during the Initial Period or during any Subsequent Period, then such
excess redemption requests will be applied in the order received by the Trustee
to successive Subsequent Periods, regardless of the number of Subsequent Periods
required to redeem such interests. All redemption requests will be redeemed in
the order in which the trustee receives the redemption request. To obtain
repayment pursuant to a redemption request, the Representative must provide to
the Participant (i) a written request for repayment signed by the
Representative, and such signature must be guaranteed by a member firm of a
registered national securities exchange or of the National Association of
Securities Dealers, Inc. ("NASD") or a commercial bank or trust company having
an office or correspondent in the United States, (ii) appropriate evidence
satisfactory to the Company and the Trustee that (A) the Representative has
authority to act on behalf of the deceased Beneficial Owner, (B) the death of
such Beneficial Owner has occurred and (C) the deceased was the owner of a
beneficial interest in such Series T bond at the time of death, (iii) if
applicable, a properly executed assignment or endorsement, and (iv) if the
beneficial interest in such Series T bond is held by a nominee of the deceased
Beneficial Owner, a certificate satisfactory to the Trustee from such nominee
attesting to the deceased's ownership of a beneficial interest in such Series T
bond. The Participant will provide these documents to the Trustee. All questions
as to the eligibility or validity of any exercise of redemption on behalf of a
deceased Beneficial Owner will be determined by the Company, in its sole
discretion, which determinations will be final and binding on all parties.

     For purposes of this Section 4.04, an interest in Series T bonds held in
tenancy by the entirety, joint tenancy or by tenants in common will be deemed to
be held by a single Beneficial Owner and the death of a tenant by the entirety,
joint tenant or tenant in common will be deemed the death of a Beneficial Owner.
The death of a Person who, during his lifetime, was entitled to substantially
all of the rights of a Beneficial Owner of an interest in the Series T bonds
will be deemed the death of the Beneficial Owner, regardless of the recordation
of such interest on the records of the Participant, if such rights can be
established to the satisfaction of the Participant, if any, and the Company.

     In the case of any redemption request which is presented pursuant to this
Section 4.04 and which has not been fulfilled at the time the Company gives
notice of its election to partially redeem Series T bonds pursuant to Section
4.02 hereof, such interest or portion thereof shall not be subject to redemption
pursuant to such Section

                                       20


4.02, but shall remain subject to redemption pursuant to this Section 4.04.


                                 ARTICLE FIFTH
                         SPECIAL INSURANCE PROVISIONS

     Section 5.01.  Insurer as Third Party Beneficiary. To the extent that the
Indenture confers upon or gives or grants to the Insurer any right, remedy or
claim, the Insurer is hereby explicitly recognized as being a third-party
beneficiary hereunder and may enforce any such right remedy or claim conferred,
given or granted hereunder.

     Section 5.02.  Notices and Information.

          (a)  The Company shall furnish to the Insurer:

          (i)  Any notice that is required to be given to a Holder of the Series
          T bonds or to the Trustee pursuant to the Indenture.

          (ii) As soon as practicable after the filing thereof, a copy of any
          financial statement of the Company and a copy of any audit and annual
          report of the Company; a copy of any notice to be given to the
          Registered Owners of the Series T bonds including, without limitation,
          notice of any redemption of or defeasance of the Series T bonds; and
          such additional information as it may reasonably request.

          (b)  The Company will permit the Insurer to have access to and to make
copies of all books and records relating to the Series T bonds at any reasonable
time.

          (c)  Notwithstanding any other provision of the Indenture, the Trustee
and the Company shall immediately notify the Insurer in accordance with Section
5.06 if at any time after such amounts are due to be paid to the Trustee or
Paying Agent there are insufficient moneys to make any payments of principal
and/or interest as required and promptly upon the occurrence of any Event of
Default hereunder.

     All notices and information required to be given to the Insurer shall be in
writing and shall be sent by overnight delivery to MBIA Insurance Corporation,
113 King Street, Armonk, New York 10504.

     Section 5.03.  Concerning the Special Insurance Provisions. The provisions
of this Article V shall apply notwithstanding anything in the Indenture to the
contrary, but only so long as the Policy shall be in full force and effect and
the Insurer is not in default thereunder.

     Section 5.04.  Amendments. Any provision of the Indenture may not be
amended in any manner which materially adversely affects the rights of the
Insurer hereunder without the prior written consent of the

                                       21


Insurer, which shall not be unreasonably withheld, conditioned or delayed.

          Section 5.05.  Limitation on Defeasance. Notwithstanding anything
herein to the contrary, in the event that the principal and/or interest due on
the Series T bonds shall be paid by the Insurer pursuant to the Policy, the
Series T bonds shall remain outstanding for all purposes, not be defeased or
otherwise satisfied and not be considered paid by the Company, and the
assignment and pledge of moneys held in trust by the Trustee and all covenants,
agreements and other obligations of the Company to the Registered Owners shall
continue to exist and shall run to the benefit of the Insurer, and the Insurer
shall be subrogated to the rights of such Registered Owners.

          Section 5.06.  Payments Under the Policy.

          (a)  If, as of the second day next preceding any date on which payment
of principal of or interest on the Series T bonds is due, there are insufficient
moneys available under the Indenture to pay all principal and interest coming
due on the Series T bonds on the next succeeding payment date, the Trustee shall
immediately notify the Insurer or its designee by telephone or telegraph,
confirmed in writing by registered or certified mail, of the amount of the
deficiency.

          (b)  If the deficiency is made up in whole or in part prior to or on
the Interest Payment Date or the date designated for the payment of principal of
the Series T bonds, the Trustee shall so notify the Insurer or its designee.

          (c)  In addition, if the Trustee has notice that any of the Registered
Owners have been required to disgorge payments of principal or interest on
Series T bonds to the Company or to the trustee in bankruptcy for creditors or
others pursuant to a final judgment by a court of competent jurisdiction that
such payment constitutes a voidable preference to such Registered Owners within
the meaning of any applicable bankruptcy laws, then the Trustee shall notify the
Insurer or its designee of such fact by telephone or telegraphic notice,
confirmed in writing by registered or certified mail.

          (d)  The Trustee is hereby irrevocably designated, appointed, directed
and authorized to act as attorney-in-fact for Registered Owners of the Series T
bonds as follows:

               (i) if and to the extent there is a deficiency in amounts
          required to pay interest on the Series T bonds, the Trustee shall (A)
          execute and deliver to State Street Bank and Trust Company, N.A., or
          its successors under the Policy (the "Insurance Paying Agent"), in
          form satisfactory to the Insurance Paying Agent, an instrument
          appointing the Insurer as agent for such Registered Owners in any
          legal proceeding related to the payment of such interest and an
          assignment to the Insurer of the claims for

                                       22


          interest to which such deficiency relates and which are paid by the
          Insurer, (B) receive as designee of the respective Registered Owners
          (and not as Trustee) in accordance with the tenor of the Policy
          payment from the Insurance Paying Agent with respect to the claims for
          interest so assigned and (C) disburse the same to such respective
          Registered Owners; and

               (ii) if and to the extent of a deficiency in amounts required to
          pay principal of the Series T bonds, the Trustee shall (A) execute and
          deliver to the Insurance Paying Agent an instrument appointing the
          Insurer as agent for such Registered Owner in any legal proceeding
          relating to the payment of such principal and an assignment to the
          Insurer of any of the Series T bonds surrendered to the Insurance
          Paying Agent of so much of the principal amount thereof as has not
          previously been paid or for which moneys are not held by the Trustee
          and available for such payment (but such assignment shall be delivered
          only if payment from the Insurance Paying Agent is received), (B)
          receive as designee of the respective Registered Owners (and not as
          Trustee) in accordance with the tenor of the Policy payment therefor
          from the Insurance Paying Agent and (C) disburse the same to such
          Registered Owners.

          (e)  Payments with respect to claims for interest on and principal of
Series T bonds disbursed by the Trustee from proceeds of the Policy shall not be
considered to discharge the obligation of the Company with respect to such
Series T bonds as set forth in Section 2.01 hereof, and the Insurer shall become
the owner of such unpaid Series T bond and claims for interest in accordance
with the tenor of the assignment made to it under the provisions of this
subsection or otherwise.

          (f)  Irrespective of whether any such assignment is executed and
delivered, the Company and the Trustee hereby agree for the benefit of the
Insurer that:

               (i)  they recognize that to the extent the Insurer makes
          payments, directly or indirectly (as by paying through the Trustee),
          on account of principal of or interest on the Series T bonds, the
          Insurer will be subrogated to the rights of such Registered Owners to
          receive the amount of such principal and interest from the Company,
          with interest thereon as provided and solely from the sources stated
          in the Indenture and the Series T bonds; and

               (ii) they will accordingly pay to the Insurer the amount of such
          principal and interest (including principal and interest recovered
          under subparagraph (ii) of the first paragraph of the Policy, which
          principal and interest shall be deemed past due and not to have been
          paid), with interest thereon as provided in the Indenture and the
          Series T bond, but only from the sources and in the manner provided
          herein for the payment of principal of and

                                       23


          interest on the Series T bonds to Registered Owners and will otherwise
          treat the Insurer as the owner of such rights to the amount of such
          principal and interest.

          Section 5.07.  Insurer's Rights Concerning the Trustee.

          (a)  The Insurer shall receive prompt written notice of any Trustee or
Paying Agent resignation.

          (b)  Notwithstanding any other provision of the Indenture, in
determining whether the rights of the Holders of Series T bonds will be
adversely affected in any material respect by any action taken pursuant to the
terms and provisions of the Indenture, the Trustee or Paying Agent shall
consider the effect on the Holders of Series T bonds as if there were no Policy.

          Section 5.08.  Insurer's Right to Accelerate, etc.  Anything in the
Indenture to the contrary notwithstanding, upon the occurrence and continuance
of an Event of Default, so long as the Policy shall be in full force and effect
and the Insurer is not in default under the terms of the Policy, the Insurer
shall be entitled to control and direct the enforcement of all rights and
remedies granted to the Holders of Series T bonds.


                                 ARTICLE SIXTH
           PARTICULAR PROVISIONS RELATED TO THE TRUST INDENTURE ACT

          Anything contained elsewhere in the Indenture notwithstanding, so long
as any of the Series T bonds shall remain outstanding, the following provisions,
which are intended to clarify certain matters, including compliance with the
TIA, shall apply, in addition to all other provisions of the Indenture, as
supplemented, and in the case of any conflict with any other provision of the
Indenture, the following provisions shall control.

          Section 6.01.  Deposited Moneys to be Held in Trust by Trustee.
Subject to Section 6.03, all moneys deposited with the Trustee pursuant to
Section 66 of the Original Indenture, shall be held in trust and applied by it
to the payment, either directly or through any Paying Agent (including the
Company if acting as its own Paying Agent), to the Registered Owners of the
particular Series T bonds for the payment or redemption of which such moneys
have been deposited with the Trustee of all sums due and to be come due thereon
for principal and interest.

          Section 6.02.  Paying Agent to Repay Moneys Held.  Upon the
satisfaction and discharge of the Indenture, all moneys then held by any Paying
Agent for the Series T bonds (other than the Trustee) shall, upon written demand
by the Company, be repaid to the Company or paid to the Trustee, and thereupon
such Paying Agent shall be released from all further obligations with respect to
such moneys.

                                       24


     Section 6.03.  Return of Unclaimed Moneys. Any moneys deposited with or
paid to the Trustee for payment of the principal of or any interest on any
Series T bonds and not applied but remaining unclaimed by the Registered Owners
of such Series T bonds for two years after the date upon which the principal of
or any interest on such Series T bonds, as the case may be, shall have become
due and payable, shall be repaid to the Company, subject to applicable abandoned
property laws, by the Trustee on written demand by the Company; and any
Registered Owner of any of such Series T bonds shall thereafter look only to the
Company for any payment which such Registered Owner may be entitled to collect.

     Section 6.04.  Provisions as to Paying Agent. The Trustee shall be the
Paying Agent for the Series T bonds and, at the option of the Company, the
Company may appoint additional Paying Agents (including without limitation
itself). Whenever the Company shall appoint a Paying Agent other than the
Trustee with respect to the Series T bonds, it will cause such Paying Agent to
execute and deliver to the Trustee an instrument in which such agent shall agree
with the Trustee, subject to the provisions of this Section:

     (a)  that such Paying Agent will hold all sums received by it as such agent
for the payment of the principal of or interest, if any, on the Series T bonds
(whether such sums have been paid to it by the Company or by any other obligor
on the Series T bonds) in trust for the benefit of the Registered Owners of the
Series T bonds, or of the Trustee until such sums shall be paid to such
Registered Owners or otherwise disposed of as herein provided;

     (b)  that such Paying Agent will give the Trustee notice of any failure by
the Company (or by any other obligor on the Series T bonds) to make any payment
of the principal of, premium if any, or interest on the Series T bonds when the
same shall be due and payable; and

     (c)  that such Paying Agent will at any time during the continuance of any
such failure, upon the written request of the Trustee, forthwith pay to the
Trustee all sums so held in trust by such Paying Agent.

     The Company will, on or prior to each due date of the principal of and any
interest on the Series T bonds, deposit with the Paying Agent a sum sufficient
to pay such principal and any interest so becoming due, such sum to be held in
trust for the benefit of the Registered Owners of the Series T bonds entitled to
such principal of and any interest, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of any failure to take
such action.

     If the Company shall act as its own Paying Agent with respect to the Series
T bonds, it will, on or before each due date of the principal of or interest, if
any, on the Series T bonds, set aside,

                                       25


segregate and hold in trust for the benefit of the Registered Owners of the
Series T bonds, a sum sufficient to pay such principal or interest, if any, so
becoming due until such sums shall be paid to such Registered Owners or
otherwise disposed of as herein provided. The Company will promptly notify the
Trustee of any failure to take such action.

     The Company may at any time pay or cause to be paid to the Trustee all sums
held in trust by it or any Paying Agent hereunder, as required by this Section,
such sums to be held by the Trustee upon the trusts herein contained, and, upon
such payment by any Paying Agent to the Trustee, such Paying Agent shall be
released from all further liability with respect to such money.

     Anything in this Section to the contrary notwithstanding, the agreement to
hold sums in trust as provided in this section is subject to the provisions of
Sections 6.02 and 6.03.

     Section 6.05.  Certificates and Notice to Trustee.  The Company shall, on
or before the expiration of ninety (90) days after the end of each calendar year
ending on or after December 31, 1999, deliver to the Trustee a certificate from
its principal executive officer, principal financial officer or principal
accounting officer covering the preceding calendar year and stating whether or
not, to the knowledge of such Person, the Company has complied with all
conditions and covenants under the Indenture, and, if not, describing in
reasonable detail any failure by the Company to comply with any such conditions
or covenants.  For purposes of this Section, compliance shall be determined
without regard to any period of grace or requirement of notice provided under
the Indenture.  Upon the occurrence of a default, the Company shall promptly
notify the Trustee of such event.

     Section 6.06.  Company to Furnish Registered Owner Lists.  The Company and
any other obligor on the Series T bonds shall furnish or cause to be furnished
to the Trustee a list in such form as the Trustee may reasonably require of the
names and addresses of the Registered Owners of the Series T bonds:

     (a)  semi-annually and not more than fifteen (15) days after each Regular
Record Date for each Interest Payment Date that is not a maturity date, as of
such Regular Record Date, and such list need not include information received
after such date; and

     (b)  at such other times as the Trustee may request in writing, within
thirty (30) days after receipt by the Company of any such request, as of a date
not more than fifteen (15) days prior to the time such information is furnished,
and such list need not include information received after such date; provided
that if and so long as the Trustee shall be the registrar for the Series T
bonds, such list shall not be required to be furnished.

                                       26


     Section 6.07.  Preservation and Disclosure of Registered Owner Lists.

     (a)  The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of the Registered
Owners of the Series T bonds (i) contained in the most recent lists furnished to
it as provided in Section 6.06, (ii) received by it in the capacity of registrar
for the Series T bonds, if so acting, and (iii) filed with it within the two
preceding years pursuant to Section 6.09(d)(ii).  The Trustee may destroy any
list furnished to it as provided in Section 6.06 upon receipt of a new list so
furnished.

     (b)  In case three or more Registered Owners of Series T bonds (hereinafter
referred to as "applicants") apply in writing to the Trustee and furnish to the
Trustee reasonable proof that each such applicant has owned a Series T bond for
a period of at least six months preceding the date of such application, and such
application states that the applicants desire to communicate with other
Registered Owners of Series T bonds with respect to their rights under this
Indenture or under the Series T bonds and such application is accompanied by a
copy of the form of proxy or other communication which such applicants propose
to transmit, then the Trustee shall, within five Business Days after the receipt
of such application, at its election, either

               (i)  afford to such applicants access to the information
          preserved at the time by the Trustee in accordance with the provisions
          of subsection (a) of this Section; or

               (ii) inform such applicants as to the approximate number of
          Registered Owners whose names and addresses appear in the information
          preserved at the time by the Trustee, in accordance with the
          provisions of such subsection (a) and as to the approximate cost of
          mailing to such Registered Owners the form of proxy or other
          communication, if any, specified in such application.

     If the Trustee shall elect not to afford to such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Registered Owner of Series T bonds, whose name and address appears
in the information preserved at the time by the Trustee in accordance with the
provisions of such subsection (a) a copy of the form of proxy or other
communication which is specified in such request, with reasonable promptness
after a tender to the Trustee of the material to be mailed and of payment, or
provision for the payment, of the reasonable expenses of mailing, unless within
five (5) days after such tender the Trustee shall mail to such applicants and
file with the Commission, together with a copy of the material to be mailed, a
written statement to the effect that, in the opinion of the Trustee, such
mailing would be contrary to the

                                       27


best interests of the Registered Owners or would be in violation of applicable
law. Such written statement shall specify the basis of such opinion. If the
Commission, after opportunity for a hearing upon the objections specified in the
written statement so filed, shall enter an order refusing to sustain any of such
objections or if, after the entry of an order sustaining one or more of such
objections, the Commission shall find, after notice and opportunity for hearing,
that all the objections so sustained have been met, and shall enter an order so
declaring, the Trustee shall mail copies of such material to all such Registered
Owners with reasonable promptness after the entry of such order and the renewal
of such tender; otherwise the Trustee shall be relieved of any obligation or
duty to such applicants respecting their application.

     (c)  Each and every Registered Owner of a Series T bond, by receiving and
holding the same, agrees with the Company and the Trustee that neither the
Company nor the Trustee nor the agent of the Company or the Trustee shall be
held accountable by reason of the disclosure of any such information as to the
names and addresses of the Registered Owners of Series T bonds in accordance
with the provisions of subsection (b) of this Section, regardless of the source
from which such information was derived, and that the Trustee shall not be held
accountable by reason of mailing any material pursuant to a request made under
such subsection (b).

     Section 6.08.  Reports by the Company.  The Company shall:

     (a)  file with the Trustee, within fifteen (15) days after the Company is
required to file the same with the Commission, copies of the annual reports and
of the information, documents and other reports (or copies of such portions of
any of the foregoing as the Commission may from time to time by rules and

     (c)  transmit by mail to all Registered Owners of Series T bonds, within

(a) and (b) of this Section as may be required by rules and regulations
prescribed from time to time by the Commission.

     Section 6.09.  Reports by the Trustee.

     (a)  Annually, not later than August 15 of each year, the Trustee shall
transmit by mail in the manner provided in Section 6.22 a brief report dated as
of such date that complies with Section 313(a) of the TIA (to the extent
required by such Section).

     (b)  The Trustee shall from time to time transmit by mail brief reports
that comply, both in content and date of delivery, with Section 313(b) of the
TIA (to the extent required by such Section).

     (c)  A copy of each such report mailed pursuant to this section shall, at
the time of such transmission to such Registered Owners, be filed by the Trustee

     (d)  Reports pursuant to this Section shall be transmitted:

          names and addresses appear in the register for the Series T bonds;

          within the two years preceding such transmission, filed their names
          and addresses with the Trustee for such purpose;

          (iii) by mail, except in the case of reports pursuant to Section
          6.09(b) and (c) hereof, to all Registered Owners of Series T bonds
          whose names and addresses have been furnished to or received by the
          Trustee pursuant to Section 6.06 and 6.07(a) (ii) hereof; and

          (iv)  at the time such report is transmitted to the Registered Owners
          of the Series T bonds, to each exchange on which Series T bonds are
          listed and also with the Commission.

     Section 6.10.  Prohibition of Impairment of Registered Owner's Right to
Payment.  Notwithstanding any other provision in the Indenture, the rights of
any Registered Owner of any Series T bond to receive payment of the principal of
and any interest on a Series T bond, on or after the respective due dates
expressed in a Series T

                                       29


bond or on the applicable Redemption Date, or to institute suit for the
enforcement of any such payment on or after such respective dates are absolute
and unconditional, and shall not be impaired or affected without the consent of
such Registered Owner.

     Section 6.11.  Notice of Default. The Trustee shall, within ninety (90)
days after the occurrence of a default with respect to the Series T bonds, give
to all Registered Owners of the Series T bonds, in the manner provided in
Section 6.22, notice of such default known to the Trustee, unless such default
shall have been cured or waived before the giving of such notice, the term
"default" for the purpose of this Section 6.11 being hereby defined to be any
event which is or after notice or lapse of time or both would become an Event of
Default; provided that, except in the case of default in the payment of the
principal of or any premium or interest on any of the Series T bonds, or in the
payment of any sinking or purchase fund installments, the Trustee shall be
protected in withholding such notice if and so long as its board of directors or
trustees, executive committee, or a trust committee of directors or trustees or
Responsible Officers in good faith determines that the withholding of such
notice is in the interests of the Registered Owners of the Series T bonds.

     Section 6.12.  Undertaking to Pay Costs. All parties to this Twentieth
Supplemental Indenture agree, and each Registered Owner of any Series T bond by
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
the Indenture (including this Twentieth Supplemental Indenture) or in any suit
against the Trustee for any action taken, suffered or omitted by it as Trustee,
the filing by any party litigant in such suit of an undertaking to pay the costs
of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but this Section 6.12 shall not apply to any suit
instituted by the Trustee, or to any suit instituted by any Registered Owner, or
group of Registered Owners, holding in the aggregate more than 10% in principal
amount of the Series T bonds outstanding, or to any suit instituted by any
Registered Owner for the enforcement of the payment of the principal of or any
interest on any Series T bond on or after the due date expressed in such Series
T bond or the applicable Redemption Date.

     Section 6.13.  Conflicting Interest of Trustee. The Trustee shall be
subject to and shall comply with the provisions of Section 310(b) of the TIA.
Nothing in this Twentieth Supplemental Indenture shall be deemed to prohibit the
Trustee or the Company from making any application permitted pursuant to such
section.

     Section 6.14.  Existence and Eligibility of Trustee. There shall at all
times be a Trustee hereunder which Trustee shall at all times be a corporation
organized and doing business under the laws of the

                                       30


United States or any State thereof or of the District of Columbia having (or in
the case of a subsidiary of a bank holding company, its parent shall have) a
combined capital and surplus of at least $50,000,000 and which is authorized
under such laws to exercise corporate trust powers and is subject to supervision
or examination by Federal or State authorities. Such corporation shall have its
principal place of business in the Borough of Manhattan, The City of New York,
State of New York or the City of Boston, Commonwealth of Massachusetts, if there
be such a corporation in such location willing to act upon reasonable and
customary terms and conditions. If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid authority, then for the purposes of this Section 6.14, the combined
capital and surplus shall be deemed to be as set forth in its most recent report
of condition so published. No obligor upon the Series T bonds or Person directly
or indirectly controlling, controlled by, or under common control with such
obligor shall serve as Trustee. If at any time the Trustee shall cease to be
eligible in accordance with this Section 6.14, the Trustee shall resign
immediately in the manner and with the effect specified herein.

     Section 6.15.  Resignation or Removal of Trustee.

     (a)  Pursuant to the provisions of this Twentieth Supplemental Indenture,
the Trustee may at any time resign and be discharged of the trusts created by
the Indenture by giving written notice to the Company specifying the day upon
which such resignation shall take effect, and such resignation shall take effect
immediately upon the later of the appointment of a successor trustee and such
day.

     (b)  Any Trustee may be removed at any time by an instrument or concurrent
instruments in writing filed with such Trustee and signed and acknowledged by
the Registered Owners of a majority in principal amount of the then outstanding
First Mortgage Bonds or by their attorneys in fact duly authorized.

     (c)  So long as no default has occurred and is continuing, and no event has
occurred and is continuing that, with the giving of notice or the lapse of time
or both, would become a default, the Company may remove any Trustee upon written
notice to the Registered Owner of each Series T bond outstanding and the Trustee
and appoint a successor Trustee meeting the requirements of Section 6.14.  The
Company or the successor Trustee shall give notice to the Registered Owners, in
the manner provided in Section 6.22, of such removal and appointment within
thirty (30) days of such removal and appointment.

     (d)  If at any time (i) the Trustee shall cease to be eligible in
accordance with Section 6.14 hereof and shall fail to resign after a written
request therefor by the Company or by any Registered Owner who has been a bona
fide Registered Owner for at least six months, (ii) the Trustee shall fail to
comply with Section 6.13 hereof after written request therefor by the Company or
any such Registered Owner,

                                       31


or (iii) the Trustee shall become incapable of acting or shall be adjudged a
bankrupt or insolvent or a receiver of the Trustee or its property shall be
appointed or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation, then the Trustee may be removed forthwith by an instrument or
concurrent instruments in writing filed with the Trustee and either:

               (i)  signed by the President or any Vice President of the Company
          and attested by the Secretary or an Assistant Secretary of the
          Company; or

               (ii) signed and acknowledged by the Registered Owners of a
          majority in principal amount of outstanding Series T bonds or by their
          attorneys in fact duly authorized.

     (e)  Any resignation or removal of the Trustee shall not become effective
until acceptance of appointment by the successor Trustee as provided in Section
6.16 hereof.

     Section 6.16.  Appointment of Successor Trustee.

          (a)  If at any time the Trustee shall resign or be removed, the
Company, by a resolution of its Board of Directors, shall promptly appoint a
successor Trustee.

          (b)  The Company shall provide written notice of its appointment of a
successor Trustee to the Registered Owner of each Series T bond outstanding
following any such appointment.

          (c)  If no appointment of a successor Trustee shall be made pursuant
to Section 6.16(a) hereof within sixty (60) days after appointment shall be
required, any Registered Owner or the resigning Trustee may apply to any court
of competent jurisdiction to appoint a successor Trustee. Said court may
thereupon after such notice, if any, as such court may deem proper and
prescribe, appoint a successor Trustee.

          (d)  Any Trustee appointed under this Section 6.16 as a successor
Trustee shall be a bank or trust company eligible under Section 6.14 hereof and
qualified under Section 6.13 hereof.

     Section 6.17.  Acceptance by Successor Trustee.

          (a)  Any successor Trustee appointed as provided in Section 6.16
hereof shall execute, acknowledge and deliver to the Company and to its
predecessor Trustee an instrument accepting such appointment hereunder, and
thereupon the resignation or removal of the predecessor Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as Trustee herein; but
                                       32


nevertheless, on the written request of the Company or of the successor Trustee,
the Trustee ceasing to act shall, upon payment of any amounts then due it
pursuant to Section 77 of the Original Indenture, execute and deliver an
instrument transferring to such successor Trustee all the rights and powers of
the Trustee so ceasing to act, including all right, title, and interest in the
First Mortgage Bonds. Upon request of any such successor Trustee, the Company
shall execute any and all instruments in writing in order more fully and
certainly to vest in and confirm to such successor Trustee all such rights and
powers. Any Trustee ceasing to act shall, nevertheless, retain a lien upon all
property or funds held or collected by such Trustee to secure any amounts then
due it pursuant to Section 77 of the Original Indenture.

          (b)  No successor Trustee shall accept appointment as provided in this
Section 6.17 unless at the time of such acceptance such successor Trustee shall
be qualified under Section 6.13 hereof and eligible under Section 6.14 hereof
and the Insurer shall have consented in writing to such appointment, which
consent shall not be unreasonably withheld, conditioned or delayed.

          (c)  Upon acceptance of appointment by a successor Trustee as provided
in this Section 6.17, the successor Trustee shall mail notice of its succession
hereunder to all Registered Owners of Series T bonds as the names and addresses
of such Registered Owners appear on the books of the Trustee kept for that
purpose.

     Section 6.18.  Limitations on Rights of Trustee as a Creditor.  The Trustee
shall be subject to, and shall comply with, the provisions of Section 311 of the
TIA.

     Section 6.19.  Company-Owned Series T Bonds Disregarded.  In determining
whether the Registered Owners of the requisite aggregate principal amount of
outstanding Series T bonds have concurred in any direction, consent or waiver
under the Indenture, Series T bonds which are owned by the Company or any other
obligor on the Series T bonds or by any person directly or indirectly
controlling or controlled by or under direct or indirect common control with the
Company or any other obligor on the Series T bonds shall be disregarded and
deemed not to be outstanding for the purpose of any such determination; provided
that, for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, consent or waiver, only Series T bonds which the
Trustee knows are so owned shall be so disregarded.  Series T bonds so owned
which have been pledged in good faith to third parties may be regarded as
outstanding for the purposes of this Section 6.19 if the pledgee shall establish
the pledgee's right to take action with respect to such Series T bonds and that
the pledgee is not a person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company or any such other
obligor.  In the case of a dispute as to such right, the Trustee may rely upon
an opinion of counsel (which may

                                       33


be counsel to the Company) and Officers' Certificate to establish the foregoing.

     Section 6.20.   Business Days.  Unless otherwise provided, in any case
where the date of maturity of the principal of or any interest on any Series T
bond or the date fixed for redemption of any Series T bond is not a Business
Day, then payment of such principal or any interest need not be made on such
date but may be made on the next succeeding Business Day with the same force and
effect as if made on the date of maturity or the date fixed for redemption, and,
in the case of timely payment thereof, no interest shall accrue for the period
from and after such Interest Payment Date or the date on which the principal of
the Series T bond is required to be paid.

     Section 6.21.  Trust Indenture Act to Control.  If and to the extent that
any provision of the Indenture limits, qualifies or conflicts with the duties
imposed by the TIA, such required provision of the TIA shall govern.

                                       34


     Section 6.22.  Manner of Mailing Notice to Registered Owner.

     (a)  Any notice or demand which by any provision of the Indenture is
required or permitted to be given or served by the Trustee or the Company to or
on the Registered Owners of Series T bonds as the case may be, shall be given or
served by first-class mail, postage prepaid, addressed to the Registered Owners
of such Series T bonds in the register of Registered Owners, and any such notice
shall be deemed to be given or served by being deposited in a post office letter
box in the form and manner provided in this Section 6.22.  In case by reason of
the suspension of regular mail service or by reason of any other cause it shall
be impracticable to give notice to any Registered Owner by mail, then such
notification to such Registered Owner as shall be made with the approval of the
Trustee shall constitute a sufficient notification for every purpose hereunder.

     (b)  The Company shall also provide any notices required under the
Indenture by publication, but only to the extent that such publication is
required by the TIA, the rules and regulations of the Commission or any
securities exchange upon which any Series T bonds are listed.


                                ARTICLE SEVENTH

entitled to share in any payment or distribution provided in Article Sixth of

interest on all Series T bonds shall be payable as follows:

Indenture notwithstanding, and without limiting the effect of Section 7.12 of

                                       36
